"All of the passengers have been safely bussed to the concourse," DIA spokeswoman Jenny Schiavone said.

Airport crews were responding. No details on condition of the aircraft or the number of passengers were available. The National Transportation Safety Board generally gets involved in these types of events.

"An aircraft slid off of a taxiway" and "we've not received any reports of injuries," Schiavone said. "We're talking about a taxiway, not a runway."

Snow has been falling lightly around metro Denver. Airport operations still were classified as normal.
